Endpoint Health Checker — Agent Utility

A small, local Node.js 18+ utility for doing a safe first-pass reachability check on public catalog gateways.

It makes HEAD requests (with an OPTIONS fallback) and produces a JSON report. A 402 response can show that a payment gateway is reachable; it does not prove an underlying seller is legitimate, healthy, or safe to buy from.

Includes:

• the standalone checker

• a quick-start guide

• README and MIT license

It never sends payment headers, credentials, wallets, request bodies, or paid API calls.

For a hosted, on-demand version, use the HustleOS catalog-gateway-health API. This download is an offline developer utility, not a guarantee of merchant quality or a financial product.
